Knowledge and practices regarding child development among primary healthcare professionals

OBJECTIVE: To evaluate the knowledge and practices regarding child development among physicians working in primary healthcare units. METHOD: Cross-sectional descriptive study carried out at primary healthcare units in Embu, São Paulo, Brazil. Study procedures: 1) Evaluation of knowledge: test consisting of 20 multiple-choice questions on child development applied to all 31 physicians who were providing pediatric care at the primary healthcare units; 2) Evaluation of practices: semi-structured interview applied to a sample of 154 mothers/caregivers of children aged up to 36 months during follow-up visits at primary healthcare units in the municipality. For the comparisons of categorical variables (evaluation/advices about development in visits of children at different ages), the chi-square test was employed. RESULTS: The mean number of correct responses among physicians was 14.8. The error rate for seven questions was greater than 30% (sensory development, language acquisition, physiology of the nervous system, clinical and laboratory diagnosis of congenital infections and innate errors of metabolism) and the rate of correct responses was greater than 85% for four questions (motor and personal-social development markers, risk factors and genetic syndromes). Regarding practices, in 69 (45%) visits, the doctor asked the mother/caregiver's opinion about the child's development; in 80 (52%), the mother/caregiver said that the doctor assessed the development; and in 64 (42%), the mother/caregiver said that the doctor advised them on practices for child's stimulation. CONCLUSIONS: Faulty knowledge and practices regarding child development were identified among primary care professionals, indicating the need for continued education.OBJETIVO: Avaliar o conhecimento e as práticas sobre desenvolvimento infantil de médicos que atuam em Unidades Básicas de Saúde (UBS). MÉTODO: Estudo transversal, descritivo, realizado nas UBS de Embu (SP). Procedimentos do estudo: 1) avaliação do conhecimento por teste contendo 20 questões de múltipla escolha sobre desenvolvimento da criança aplicado a 31 médicos (universo) que prestam assistência pediátrica em UBS; 2) avaliação das práticas - entrevista semiestruturada aplicada para uma amostra de 154 mães/cuidadores que acompanhavam crianças com idade menor ou igual a 36 meses em consulta médica agendada em UBS do município. Para comparação de variáveis categóricas (avaliação/orientações sobre desenvolvimento em consultas de crianças de diferentes faixas etárias), utizou-se o qui-quadrado. RESULTADOS: A média de acertos dos médicos foi de 14,8 questões; sete questões apresentaram índices de erros superiores a 30% (desenvolvimento sensorial, aquisição de linguagem, fisiologia do sistema nervoso, diagnóstico clínico e laboratorial de infecções congênitas, erros inatos do metabolismo) e quatro questões apresentaram acertos acima de 85% (marcos do desenvolvimento motor, pessoal-social, fatores de risco e síndrome genética). Quanto às práticas, em 69 (45%) consultas o médico perguntou a opinião da mãe/cuidador sobre o desenvolvimento da criança, em 80 (52%) a mãe/cuidador referiu que o médico fez alguma pergunta e/ou avaliou o desenvolvimento e em 64 (42%) orientou sobre como estimular a criança. CONCLUSÕES: Identificaram-se falhas de conhecimento e nas práticas dos profissionais referentes ao desenvolvimento da criança, o que indica a necessidade de implementar educação permanente.UNIFESP Curso de MedicinaUNIFESP Projeto DesenvolverSecretaria Municipal de Saúde do EmbuUNIFESP Departamento de Pediatria Disciplina de Pediatria Geral e ComunitáriaUNIFESP, Curso de MedicinaUNIFESP, Projeto DesenvolverUNIFESP, Depto. de Pediatria Disciplina de Pediatria Geral e ComunitáriaSciEL

Television viewing in Thai infants and toddlers: impacts to language development and parental perceptions

<p>Abstract</p> <p>Background</p> <p>Effects of television to language development in infants and toddlers, especially in the Asian children, are inconclusive. This study aimed to (a) study time spent on television in Thai infants and toddlers (age < 2 years), (b) investigate the association between time spent on television (as recommended by the American Academy of Paediatrics (AAP), < 2 hours per day) and language development in Thai 2-year-old children, and (c) explore parental perceptions on television toward their child's development.</p> <p>Methods</p> <p>Two hundred and sixty children and their parents were recruited into the study. Time spent on television and parental perceptions on television viewing toward their child's development were recorded during face-to-face and telephone interviews. Language development was assessed at the age of 2 years using the Clinical Linguistic Auditory Milestone Scale (CLAMS), and parents' report. Association between delayed language development and time spent on television viewing, as well as other various parameters such as gender, maternal education and family income, were analysed using a multivariate logistic regression model.</p> <p>Results</p> <p>Most Thai infants and toddlers watched television at the age of 6 months, 1 year and 2 years old (98.0, 95.3 and 96.7%, respectively). On average, 1-year-old children watched television 1.23 ± 1.42 hours per day. This increased to 1.69 ± 1.56 hours per day when they were 2 years old. However, watching television longer than 2 hours per day did not associate with delayed language development. On multivariate logistic regression analysis, gender (male) was the only significant factor associated with delayed language development (OR = 6.9, 95% CI = 1.5–31.3). Moreover, 75%, 71%, and 66% of Thai parents believed that television viewing yielded benefits to children's developments.</p> <p>Conclusion</p> <p>Thai children commenced watching television at an early age and the amount of television viewing time increased by age. Most parents had positive perceptions to television viewing. The study found no association between time spent on television viewing (≥ 2 hours per day) and delayed language development at the age of 2 years.</p> <p>Gender (male) was the only variable associated with delayed language development.</p

Late style and speaking out: J A Symonds's In the Key of Blue

This article examines In the Key of Blue (1893)—an essay collection by John Addington Symonds—as a case study in queer public utterance during the early 1890s. Viewed through the critical lens of late style, as theorised by Edward Said, the evolution of this project, from compilation through to reader reception, reveals Symonds's determination to “speak out” on the subject of homosexuality. Paradoxically, In the Key of Blue was thus a timely and untimely work: it belonged to a brief period of increased visibility and expressiveness when dealing with male same-sex desire, spearheaded by a younger generation of Decadent writers, but it also cut against the grain of nineteenth-century social taboo and legal repression. Symonds's essay collection brought together new and previously unpublished work with examples of his writing for the periodical press. These new combinations, appearing together for the first time, served to facilitate new readings and new inferences, bringing homosexual themes to the fore. This article traces the dialogic structure of In the Key of Blue , its strategies for articulating homosexual desire, and examines the response of reviewers, from the hostile to celebratory

Myeloid Heme Oxygenase-1 Haploinsufficiency Reduces High Fat Diet-Induced Insulin Resistance by Affecting Adipose Macrophage Infiltration in Mice

Increased adipose tissue macrophages contribute to obesity-induced metabolic syndrome. Heme oxygenase-1 (HO-1) is a stress-inducible enzyme with potent anti-inflammatory and proangiogenic activities in macrophages. However, the role of macrophage HO-1 on obesity-induced adipose inflammation and metabolic syndrome remains unclear. Here we show that high-fat diet (HFD) feeding in C57BL/6J mice induced HO-1 expression in the visceral adipose tissue, particularly the stromal vascular fraction. When the irradiated C57BL/6J mice reconstituted with wild-type or HO-1+/− bone marrow were fed with HFD for over 24 weeks, the HO-1+/− chimeras were protected from HFD-induced insulin resistance and this was associated with reduced adipose macrophage infiltration and angiogenesis, suggesting that HO-1 affects myeloid cell migration toward adipose tissue during obesity. In vivo and in vitro migration assays revealed that HO-1+/− macrophages exhibited an impaired migration response. Chemoattractant-induced phosphorylation of p38 and focal adhesion kinase (FAK) declined faster in HO-1+/− macrophages. Further experiments demonstrated that carbon monoxide and bilirubin, the byproducts derived from heme degradation by HO-1, enhanced macrophage migration by increasing phosphorylation of p38 and FAK, respectively. These data disclose a novel role of hematopoietic cell HO-1 in promoting adipose macrophage infiltration and the development of insulin resistance during obesity

Heme Oxygenase-1 Accelerates Cutaneous Wound Healing in Mice

Heme oxygenase-1 (HO-1), a cytoprotective, pro-angiogenic and anti-inflammatory enzyme, is strongly induced in injured tissues. Our aim was to clarify its role in cutaneous wound healing. In wild type mice, maximal expression of HO-1 in the skin was observed on the 2nd and 3rd days after wounding. Inhibition of HO-1 by tin protoporphyrin-IX resulted in retardation of wound closure. Healing was also delayed in HO-1 deficient mice, where lack of HO-1 could lead to complete suppression of reepithelialization and to formation of extensive skin lesions, accompanied by impaired neovascularization. Experiments performed in transgenic mice bearing HO-1 under control of keratin 14 promoter showed that increased level of HO-1 in keratinocytes is enough to improve the neovascularization and hasten the closure of wounds. Importantly, induction of HO-1 in wounded skin was relatively weak and delayed in diabetic (db/db) mice, in which also angiogenesis and wound closure were impaired. In such animals local delivery of HO-1 transgene using adenoviral vectors accelerated the wound healing and increased the vascularization. In summary, induction of HO-1 is necessary for efficient wound closure and neovascularization. Impaired wound healing in diabetic mice may be associated with delayed HO-1 upregulation and can be improved by HO-1 gene transfer

The Mayer-Rokitansky-Küster-Hauser syndrome (congenital absence of uterus and vagina) – phenotypic manifestations and genetic approaches

The Mayer-Rokitansky-Küster-Hauser (MRKH) syndrome affects at least 1 out of 4500 women and has for a long time been considered as a sporadic anomaly. Congenital absence of upper vagina and uterus is the prime feature of the disease which, in addition, is often found associated with unilateral renal agenesis or adysplasia as well as skeletal malformations (MURCS association). The phenotypic manifestations of MRKH overlap various other syndromes or associations and thus require accurate delineation. Since MRKH manifests itself in males, the term GRES syndrome (Genital, Renal, Ear, Skeletal) might be more appropriate when applied to both sexes. The MRKH syndrome, when described in familial aggregates, seems to be transmitted as an autosomal dominant trait with an incomplete degree of penetrance and variable expressivity. This suggests the involvement of either mutations in a major developmental gene or a limited chromosomal deletion. Until recently progress in understanding the genetics of MRKH syndrome has been slow, however, now HOX genes have been shown to play key roles in body patterning and organogenesis, and in particular during genital tract development. Expression and/or function defects of one or several HOX genes may account for this syndrome

Astrocytes: biology and pathology

Astrocytes are specialized glial cells that outnumber neurons by over fivefold. They contiguously tile the entire central nervous system (CNS) and exert many essential complex functions in the healthy CNS. Astrocytes respond to all forms of CNS insults through a process referred to as reactive astrogliosis, which has become a pathological hallmark of CNS structural lesions. Substantial progress has been made recently in determining functions and mechanisms of reactive astrogliosis and in identifying roles of astrocytes in CNS disorders and pathologies. A vast molecular arsenal at the disposal of reactive astrocytes is being defined. Transgenic mouse models are dissecting specific aspects of reactive astrocytosis and glial scar formation in vivo. Astrocyte involvement in specific clinicopathological entities is being defined. It is now clear that reactive astrogliosis is not a simple all-or-none phenomenon but is a finely gradated continuum of changes that occur in context-dependent manners regulated by specific signaling events. These changes range from reversible alterations in gene expression and cell hypertrophy with preservation of cellular domains and tissue structure, to long-lasting scar formation with rearrangement of tissue structure. Increasing evidence points towards the potential of reactive astrogliosis to play either primary or contributing roles in CNS disorders via loss of normal astrocyte functions or gain of abnormal effects. This article reviews (1) astrocyte functions in healthy CNS, (2) mechanisms and functions of reactive astrogliosis and glial scar formation, and (3) ways in which reactive astrocytes may cause or contribute to specific CNS disorders and lesions

Internal Migration, Sport and the Scottish Diaspora in England.

Sport has been argued to play an important role for members of diasporic groups of various origins and in various locations (Burdsey, 2006; Carrington, 2010; Darby and Hassan, 2008; Kaufman, 2005). However, little attention has been paid to the role sport plays for ‘internal migrants’ who migrate to contrasting locations within a nation-state, despite the potential for significant contrasts in the prevailing sporting cultures found in different regions of the same nation-state. This article therefore aims to make a contribution towards understanding this relationship by reflecting upon the role sport plays for members of the Scottish diaspora living in England, drawing upon interviews and personal reflections from a number of Scottish ‘internal migrants’ located within the United Kingdom. In particular, discussion attempts to draw attention to the central role sport plays for these individuals in order to maintain a cultural attachment with their Scottish birthplace, given the relative lack of other cultural practices or associations which could be used to achieve this goal. Comparisons are also drawn with studies of the Scottish diaspora in more distant geographic contexts, as well as similar diasporic groups in the English context such as the Irish diaspora. These comparisons allow for a consideration of the impact of geographic proximity and cultural proximity on the relative importance of sport and other cultural practices for Scots living in England, identifying a number of important issues for those studying the role played by sport in the maintenance of a cultural attachment with ‘home’ for various diasporic groups
